php-mysqlHow to set a timeout for MySQL query in PHP?

The mysqli_query() function in PHP can be used to set a timeout for a MySQL query. The timeout parameter of the function can be used to set the timeout value in seconds.

$mysqli = new mysqli("localhost", "user", "password", "database");
$query = "SELECT * FROM table";
$result = $mysqli->query($query, MYSQLI_STORE_RESULT, MYSQLI_OPT_CONNECT_TIMEOUT, 10);

The output of the above code will be a mysqli_result object if the query is successful, or FALSE if the query times out.

Code explanation

• $mysqli = new mysqli("localhost", "user", "password", "database");: This line creates a new mysqli object with the given parameters.
